Application filed November 18, 1913. Serial No. 801,693.

Vand itsobject is to produce a device of this class that is simple in construction, cheap to manufacture, eilicient in operation. With the foregoing Vand other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claim and illustrated in the accompanying drawing which forms a part of said specification and in which#- Figure 1 is a side elevation ofmy` invention in section.

Fig. 2 is a section taken on line 2 2 of llig. 1.

Like reference characters indicate corresponding parts throughout the several views.

1 is an' air chamber provided with the screw cap 2 which is apertured to permit free movement of the plunger 3 which extends through the said air chamber. Within the air chamber a flexible jacket 4, made of leather or similar material, is disposed. The said jacket 4 is somewhat cylindrical in shape and open at its lower end and above and below the top of said jacket metal plates 5, 5 are disposed that serve to retain the jacket in operative relation as it is reciprocated with the piston, the said plates being threaded upon the plunger rod 3 and the jacket being apertured to permit passage of that member. Upon the plunger just below the 'top of the jacket 4 a beveled collar 6 is disposed which is threaded upon the plunger. Below said collar and abutting the same is a spring 7 which encircles said plunger and rests upon an arm 8 formed integral with or secured to the flexible steel piston 9 which is circular in shape and formed with beveled wings 10 projecting toward the center of the piston and disposed approximately 90 degrees apart about said piston. The piston is retained in position upon the plunger through the medium of the arm 8 which rests upon the washer 11 and below said washer a spring 12 encircles the plunger and rests upon a shoulder 13 of member 14 mentioned hereinafter.

The lower portion ot the air chamber is diminished in diameter as shown at 14 and terminates in a threaded port 15 adapted to receive one end of the connecting pipe 16 that at its opposite end engages the water chamber 17 which is apertured as at 18 in its base and provided with the spring-pressed check valve 19. 20 is a port formed integral with the water chamber and the said port is provided with a check valve 21 and further it is connected to the eduction pipe 22 which conveysl the liquid to a point above the level of the water chamber.

In operation the water chamber is partially or totally immersed in the liquid to be raised. Upon pressing the piston rod 3 downward the rustoconical member 6 engages the beveled portions of the arm 10,

expanding the piston 9, which presses the jacket outward and makes a tight t with the. piston. The remainder of the stroke compresses the air within the air chamber, which in turn acts upon the water within chamber 17. Upon the pressure being removed l'rom the piston rod the spring 12 forces the piston 9 upward, but at the same `time the conical member 6 is moved relatively to the piston by spring 7. Thus the piston contracts and allows sufficient elearance between the pump barrel walls and the packing to permit the entrance of air. What is claimed is The combination of a piston comprising-a piston rod, springs encircling said piston rod, a piston cylinder, an arm formed integral with said piston cylinder and engaging said piston rod between the encircling springs thereof, inwardly extending wings carried by said piston cylinder and having their free extremities beveled downwardly and inwardly, and a truste-conical member fast upon said piston rod and serving as an abutment for theuppermost of said springs, the lower face of said member being adapted for operative engagement with the beveled ends of said wings.

In testimony that l `claim the foregoing as my own I have hereto affixed my signature in the presence of two subscribing witnesses.
